l -NITED STATES 'WILLIAM F. PARADISE, 0F ATGHISON, KANSAS PROCESS OF MAKING, FREEZTNG AND HARDENING ICE CREAM AND APPARATUS THEREFOR Application led January 21, 1929. Serial No. 333,848.

This invention relates to a process of making, freezing and hardening ice cream and apparatus therefor.

The object of the invention is to make ice cream and harden the same in a relatively short time.

Another object of the invention is to make an edible composition, whiclrprefera'bly is formed of portions or bodies of different i flavors. and which mass is frozen hard in a short period. 1 e

A still further object of my process is the freezing or hardening of an edible body or ma ss by subjecting the same both interiorly d and exteriorly to a freezing action.

With the foregoing and other objects in view. my invention comprises certain novel constructions` combinations and arrangen ments 'of parts as will be hereinafter fully i 6' described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claim.

In the drawings:

'Figure l is a vertical sectional view of a mixing and chilling device, illustrating the first step of my process.

Figure 2 is a vertical sectional view of a.

device illustrating the second step of my process. Figure 3 is a vertical sectional view of a container` filled with ingredients and illustrating what might be considered the fourth step of my process. c

Figure 4 is a fragmentary view of a hardening room, with a. container therein, which container is filled with ingredients such as ice cream.

Figure 5 is a perspective view of. a plate having thereon a cross section slice or servinar of the frozen icc cream or frozen edible produced in accordance with this process.

Referring to the drawings by numerals, l designates the container of the mixing and chilling device, which is employed in mixing the ingredients of the ice cream. It is to be noted that I have shown in Figure l the conventional form of an ordinary ice cream freezer, which if surrounded with a suitable freezing' compound, such as ice and salt,

would serve to chill the ingredients in the container l.

The second step of my process entails the placing of the filled container 1 over a vat 2, and before so placing, or upon placing the container on the vat, I place a cover 3 on the container; this cover is provided with an integral open-mouth cylinder or tube 4; I use the term tube in a broad sense, meanin any suitable container that will hold the freezing compound in the body of the edible mass, such as ice cream. Further, I may use a plurality of tubes, as indicated by dotted lines 4a, and inV cross section, these tubes 4 and rz-may be of any desirable and conventional form, as indicated in Figure 5, wherein I have shown heart and diamond shape figures in the individual helping on the plate 5.

It is to be understood that the tube or tubes may be iarge enough to displace any desired proportion of the contents of the container 1. After the cover 3 is in position, as shown in Figure 2. I preferably pump or force a brine solution of. freezing temperature into the tube and allow it'toV overfiow at the top of 75 the container down and around the same, passing back into the vat 2 containing the solution, thereby applying a freezing compound or solution to the ice cream inside the container, as well as entirely around the container on the outside, whereby the ice cream is frozen hard. Y In this manner the time consumed in freezing and hardening the liquid contents of the container is greatly shortened over the common method of manufacture.

The next or third step of my process of making an inlaid body of edbles comprises the pouring of warm Water, or some other thawing solution over the container and then withdrawing or removing the'cover 3 and its tube 4. Upon the removal of the cover and its depending tube or tubes, cavity 6 (Fig. 3) will be left in the frozen or hardened mass. Then I take a suitable receptacle, such as shown at 7 filled with a different- Havoring of ice cream (from that of the main body) or Sherbert. pouring the cavity 6 full thereof, then the container l is placed in the hardening room 8 to allow the filled portion of the ice cream to harden, whereupon all of the ice cream, whether it loe of different ilevors, or ice cream and Sherbert, will `reeze Solid into one relativellx/iv herd body; this lieingr accomplished in :i Very short time.

liter the ice cream is removed from Jehe hardening room in the container L und upon cuting transversely or horizonzillli7 icioes che frozen mass, each individual serving Will produce an inlaid or motled effect, as illnetrnred in Figure 5, which is very attractive und rends to increase the salnhilitjf of die goods.
